On point 1: I don't think there is much that is more important than personalized time. I don't think 2 minutes of 1-on-1 time a day is ideal, though it's 100x better than what we have now. Something better may be if each week a teacher spends 10-15 minutes of quality time with each student, rotating who to spend time with from week to week. Still, naturally we need to try to have less students per classroom.
On point 3: Ideally there would be more autonomy, though as a first step to be significantly more successful, some slight bending of rules would do mounds.
On your conclusion and mine: I believe a major re-education of teachers would solve a lot of the issues. Most teachers think their main job is transferring knowledge in whatever subject they teach. However, in today's world where practically all knowledge is freely available, that job has been mostly taken care of. I believe a teacher's role is being a mentor for each student - assisting each student in discovering the world and their respective subject, inspiring them, freeing their minds, passing on curiosity and intrigue.
